It will always depend on how you use it.
I have driven a Kona, with similar highway range as a MYRWD, from Brisbane to North Queensland, using QESH chargers, which are almost all limited to 50kW (about 45kW in practice). It was fine, so long as I was willing to take some longer breaks, including one where I took a refreshing 30 minute nap in the air-conditioned car while it charged.
It definitely takes longer, and more planning for highway trips. That said, a Tesla can charge much faster on superchargers and ABRP shows all sorts of routes in NSW and Victoria where a day of driving needs about an hour of charging, most of it in short blocks similar to normal breaks to eat and use the bathroom.
There are inland roads that will be impractical in the MYRWD for the time being due to a lack of charging infrastructure.
Yes, any car bought now is likely to be superceded by the next generation. I reckon I will be envious of people nipping into the fast charger and leaving after 5 minutes while I take 15. But I will still get where I am going in a good time, and it will make no difference at all when I am driving around town.
The thing I am definitely going to envy is V2L, V2H and V2G capability. Being able to stop anywhere and run appliances off the car is such a cool idea. I do wish Tesla hadn't dragged their feet on that.
